In the real system you have a mass flow of droplets, in kg/s. That number goes into the injection panel, along with speed and a starting location. The speed and kg/s are NOT related for the injection as these are discrete droplets/particles.  Turn off DDPM, at 10% it's not necessary to begin with, you may need to couple the DPM model, but that also depends on the flow field. Now re-run and see what's going on.
